OF PHILADELPHIA, PENNSYL- VANIA, A CORPORATION OF PENNSYLVANIA HEDDLE-FRAME.

Specification of Letters Patent.

Patented Nov. 16, 1920.

Application filed September 3, 1919. Serial No. 321,304.

To all whom it may concern Be it known that I, JAooB KAUFMANN, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Heddle-Frames, of which the following is a specification.

My invention relates to heddle frames for looms, and it relates more particularly to improved means for strengthening or stifiening the top and bottom rails of the frame and for supporting the heddle bars intermediate their ends.

The principal object of my present invention is to provide an improved form of stay or brace for the top and bottom rails of the frame which will effectually prevent springing of the frames, and at the same time will firmly support the heddle bars intermediate their ends, thereby insuring freedom and easy play of the heddles on the heddle bars. r

My invention contemplates a form of stay or brace which can be readilyand easily attached in and detached from the frame, and whichis so constructed and arranged as to efficiently function for its intended purpose, while at the same time readily permitting the proper arrangement of the heddles in the frame. My present invention is particularly applicable to that type of heddle frames in which there are provided pairs of heddle bars at the top and bottom as is often done when the warp ends controlled by the frame are closely arranged.

The nature and characteristic features of my invention will be more readily understood from the following description taken in connection with the accompanying drawings forming part thereof, in which;

Figure 1 is a front elevation of a heddle frame provided with a stay or brace embodying the main features of my present invention Fig. 2 is an enlarged fragmentary detail view, partly in elevation and partly in section, of a portion of the structure shown in Fig. 1, illustrating the manner of connecting the stay rod to the top and bottom rails of the frame; and

Fig. 3 is a transverse section thereof taken on approximately the line 3 3 of Flg. 2, certain portions being shown in elevatlon.

Referring to the drawings, the heddle frame there shown comprises the top and bottom rails 5, usually made of wood, and connected at their respective ends by means of the end straps 6. Extending from end to end of the heddle frame, and arranged near the top and bottom rails in the usual manner are the heddle bars 7, upon which the heddles 8 are mounted and supported. The heddle bars 7 may be arranged in pairs as shown, this arrangement being provided for close installations of the Warp ends to prevent crowding of the heddles on their supporting bars.

The stay rod proper comprises a'thin fiat strip of metal 9, suitably located in the heddle-frame at desired placesintermediate the ends thereof. The stay or brace rod 9 has each end reduced in width as at 10, and for a short distance on each side of said reduced portion 10, there extendtongues 11, which provide pockets or recesses 12 in which the heddle bars 7 are supported. The tongues 11 extend a sufiicient distance to effectively prevent sidewise displacement of the heddle bars 7 in the pockets or recesses 12, the base of each slot forming a I support for one edge of the respective heddle bar 7. -Each narrow end portion 10 of the stay or brace 9 is also provided with a suitable aperture 13 which is engaged b a hooklike extension 14 of a bolt 15, which bolt 15 extends through the rail 5. The other end of the bolt 15 is threaded to receive a complementally threaded nut 16, preferably of the wingtype. A washer 17 is arranged on the bolt .15 on the outer side of the rail 5, and a split lock washer 18 is interposed between the washer 17 and the nut 16.

A metal plate 20 is secured in any suitable manner on the inner edge of the rail 5, the bolt 15 passingtherethrough. The plate 2 forms a seat for the squared end of the narrow portion 10 of the stay or brace 9, and the arrangement is such that when the parts are in their assembled positions and the bolt 15 engages the aperture 13 in the end of the stay or brace 9,.and

thawing-nut 16 is advanced on the bolt surface of the metal plate 20 above mentioned, and is provided with upwardly extending portions 23 formed by bending the metal of the plate '22 at right angles, as clearly shown in Fig. 2 of the drawings. The extensions 23 of plate 22 form shoul ders for the proper positioning of the stay or brace 9 with respect to the hook-like extension let of bolt 15, and the upper ends of the extensions 23 of plate 22 also form seats for confining the heddle bars 7, as clearly shown in Figs. 2 and 3 of the'drawings, within the pockets or recesses 12 of the stay rod 9.

It will be noted that with a device constructed as aforesaid, the stay or brace 9 may be readily removed for the purpose of arranging the heddles mounted on the bars 7, as may be required. In order to remove the stay or brace 9, it is only necessary to slack off the wing nuts 16 to allow the squared ends 21 of the stay or brace 9 to be relieved of frictional engagement with the upper surfaces of the plate 20, and also to be freed of engagement with the hooklike extensions 14: of the bolts 15, whereuponit will be apparent that the stay or brace 9 may be readily shifted with respect to said securing device, and, on account of the arrangement of the tongues 11 providing the pockets 12, which are open toward the ends of the stay rod, said stay rod may be readily disengaged from the heddle bars 7 which are supported in the recesses or pockets 12 thereof.

It will beseen that there is thus provided a simple and efficient form of stayor brace, and means for securing the same intermediate the ends of the heddle-frame, which will firmly and effectively function to prevent springing of the top and bottom rails, which will also firmly support the heddle bars 7, and maintain the same inproper positions, and which may be readily removed when desired for the purpose of permitting the insertion or rearrangement of the heddles upon the heddle bars 7. 7

Having thus described the nature and characteristic features of my invention what I claim as new, and desire to secure by Letters Patent is:
